I've noticed there's a slight difference in loot drops after completing an encounter the first time. I only did a few runs of castellum with a couple of buddies. I found that there were no exotics dropping after the first completion, no catalysts at all, and leviathan shaders only drop on the first completion. That last one isn't meaningful for loot but it gave me the idea that the loot drops change a bit. I got a handful of 2 levi shaders on the first completion and after that I just got random blue shaders. Just a few specific questions I'm curious about. 1. Is it possible to get the raid catalysts from farming checkpoint? More specifically, Is it possible to get the Acrius catalyst from farming the castellum? 2. Do exotics still have a chance to drop after the first completion of the castellum? I farmed for an hour or two with a couple buddies and we only saw one exotic drop on the first completion. I'm pretty much just trying to narrow down the loot table a bit if it differs after the first completion. I want to get a rock-solid answer as this is the sort of thing that will never really be confirmed within the community, (Ex. Skyburner's Oath may or may not drop on prestige leviathan runs). Speculation does give more insight into what could be the situation and I would rather have a rough idea than nothing at all.
